you can make 4 diff builds, support pvp, support pve, dps pve, dps pvp ... all those are pretty same but some minor changes are needed
And also depend which server, f2p or p2p ..
There are so muhc more than 4 builds to bard.
Full support example for domi could be 3 different builds.
Aswell as support dps that could be differing from pve and pvp probably up to 4 builds or more.
Aswell as dps there are about 4+ builds yo ucould be using example physical dmg and natural dmg builds.
Though you need to be an experienced bard player to be able to master all these builds i just had to put it out there
But as a beginner to bard you are good with 2 hybrid builds between pve and pvp. Like one support and one dps, that will make you more vertile in both scenarios.
